Liver regeneration after extensive hepatectomy in rats: effect of preoperative chemotherapy with intravenous 5-fluorouracil.

Purpose: To evaluate the effect of preoperative intravenous chemotherapy with 5-fluorouracil on liver regeneration in an experimental model of major hepatectomy in rats.

Methods: Wistar rats were divided into two groups of 20 animals each and submitted to 70% hepatectomy 24 h after intravenous injection of 5-fluorouracil 20 mg/kg (fluorouracil group, FG) or 0.9% saline (control group, CG).

Magnetic compression anastomosis for the treatment of complete gastric outlet obstruction due to corrosive injury.

Tensiometric evaluation of the effect of lowfrequency electric stimulation on healing Achilles tendons in rats.

Purpose: To evaluate the effects of low-frequency electric stimulation on biomechanics following surgical treatment of the Achilles tendon in rats.

Methods: Forty-two rats were divided into two groups. One was given electric stimulation and the other was not.

Conservation of both hematocrit and liver regeneration in hepatectomies: a vascular occlusion approach in rats.

Background: Hepatectomies promote considerable amount of blood loss and the need to administrate blood products, which are directly linked to higher morbimortality rates. The blood-conserving hepatectomy (BCH) is a modification of the selective vascular occlusion technique. It could be a surgical maneuver in order to avoid or to reduce the blood products utilization in the perioperative period.

Ex vivos models to teaching therapeutic endoscopic ultrasound (T-EUS).

Background: Endoscopic ultrasound training has a learning curve greater than the other endoscopic therapeutic techniques. One of the preclinical teaching methods is the use of ex vivo porcine models.

Aim: To describe five ex vivo porcine models for training in therapeutic echoendoscopic procedures.

ANALYSIS OF DOUBLE BALLOON ENTEROSCOPY: INDICATIONS, FINDINGS, THERAPEUTIC AND COMPLICATIONS.

Background: The double balloon enteroscopy is an important method for the endoscopic approach of the small bowel that provides diagnosis and therapy of this segment's disorders, with low complication rate.

Aim: Analysis of patients undergoing double balloon enteroscopy. The specific objectives were to establish the indications for this method, evaluate the findings by the double balloon enteroscopy, analyze the therapeutic options and the complications of the procedure.

AN INNOVATIVE EX-VIVO MODEL FOR RAPID CHANGE OF THE PAPILLA FOR TEACHING ADVANCED ENDOSCOPIC RETROGRADE CHOLANGIOPANCREATOGRAPHY PROCEDURES.

Background: Models for endoscopic retrograde cholangiopancreatography training allow practice with an expert feedback and without risks. A method to rapidly exchange the papilla can be time saving and accelerate the learning curve.

Aim: To demonstrate a newly method of rapid exchange papilla in ex-vivo models to teach retrograde cholangiopancreatography advanced procedures.

Ex vivo and simulator models teaching therapeutic ERCP and EUS: description of SOBED's first course.

Teaching models in endoscopy are important tools to minimize risks derived from endoscopic procedures, taking into account that therapeutic endoscopy, also known as surgical endoscopy, has greatly developed during the last decade. This results from the fact that minimally invasive procedures present relevant contributions and promote more comfort to patients. In this context, ex vivo teaching models and virtual simulators are important tools to the safe acquisition of abilities.
